Benefits of technology

The present invention is about a peritoneal dialysis catheter that is thin and flexible with a distal end connected to a catheter connector. The catheter connector has a tip that attaches to a dialysis tubing assembly with an externally threaded surface. The tip is surrounded by a cylindrical cover with a peripheral wall that shields the tip. A cap can be removably attached to the tip. The technical effects of this invention include improved dialysis efficiency, reduced risk of infection, and improved quality of life for patients with kidney failure.

Problems solved by technology

In persons with chronic renal disease the kidneys are no longer able to perform this function effectively.
The procedure was long, tedious, time consuming, and very restrictive towards the patient's lifestyle.
However, patients undergoing peritoneal dialysis can be at risk of peritonitis, a bacterial or fungal infection of the peritoneum.
Left untreated, peritonitis can lead to severe, potentially life-threatening infection throughout the body.
The catheter tip can become contaminated, for example, during the process of connecting the catheter with the dialysis tubing.
Contamination of the catheter can lead to passage of contaminants and microorganisms to the peritoneal cavity.

Embodiment Construction

[0018]Referring to FIGS. 1-5, an embodiment of a peritoneal dialysis catheter 100 is shown. The peritoneal dialysis catheter 100 can include a thin, flexible tube 110, a catheter connector 130 at a distal end of the tube 110, and a cover 120 surrounding at least a portion of the catheter connector 130. The catheter connector 130 can include a substantially rigid cylindrical body and a tip 135 extending from a free end of the catheter connector 130. For example, the cylindrical body of the catheter connector 130 can be substantially more rigid than the tube 11 and can have a diameter that is greater than the diameter of the tube 110. The tip 135 can be configured to attach to a dialysis tubing assembly 140. The tip 135 can be generally frusto-conical. The tip 135 can include an externally threaded surface, e.g., helical ridges or threaded portions disposed on an outer surface of the tip 135, to facilitate attachment to the dialysis tubing assembly 140, as discussed in detail below. T...

Abstract

The peritoneal dialysis catheter includes a thin, flexible tube, a catheter connector at a distal end of the tube, and a cylindrical cover surrounding at least a portion of the catheter connector. The catheter connector includes a tip that is configured to attach to a dialysis tubing assembly. The tip can include an externally threaded surface. A peripheral wall of the cover can surround or shield the externally threaded surface of the tip. The peritoneal dialysis catheter can include a cap, which can be removably attached to the tip.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention generally relates to infection mitigation in medical procedures and, more specifically, to a catheter for minimizing the risk of infection during peritoneal dialysis procedures.[0003]2. Description of the Related Art[0004]Normally the kidneys function to filter nitrogenous waste materials and toxins from the blood to the urine. In persons with chronic renal disease the kidneys are no longer able to perform this function effectively. For many years the only form of treatment available was a hemodialysis procedure in which the patient was connected to dialysis machine which would pump out the patient's blood, filter the waste material through a semipermeable membrane, and pump the blood back into the patient. The procedure was long, tedious, time consuming, and very restrictive towards the patient's lifestyle.[0005]In recent years, an alternative form of treatment known as peritoneal dialysis has bee...
